Description

TECHNICAL FIELD

[0001] The present application relates to the field of food and medicine packaging machinery, in particular to a material conveying device and method. BACKGROUND

[0002] Before pre-filled packaging material is fed to the unpacking machine, it needs to be sterilized by a sterilizer. Due to the limitation of factory layout and other factors, the alcohol sterilizer and the unpacking machine are usually not in the same area, so a transition conveying mechanism is needed to connect the unpacking machine and the sterilizer. The use of a servo motor in the transition conveying mechanism will increase the cost, so a general motor is usually used. However, the use of a general motor in the transition conveying mechanism and the use of a servo motor in the sterilizer and the unpacking machine will cause problems such as speed mismatch and position uncertainty between the general motor and the servo motor, which may cause the packaging material to collide with the material pushing mechanism when it enters the unpacking machine from the transition conveying mechanism.

[0026] The present application will be further described in detail below in combination with the drawings and specific embodiments of the present application.

[0027] Example one

[0028] Figure 1An embodiment of the material conveying device of the present application is shown. The material conveying device of the embodiment comprises a sterilizer discharge conveying belt 1, a transition conveying belt 2 and a bale opener feed conveying belt 3 connected in sequence. The transition conveying belt 2 is provided with a feed detection member 21 at one end close to the sterilizer discharge conveying belt 1, which is used to control the sterilizer discharge conveying belt 1 to suspend discharging and the bale opener feed conveying belt 3 to retreat. The transition conveying belt 2 is provided with a discharge detection member 22 at one end close to the bale opener feed conveying belt 3, which is used to control the sterilizer discharge conveying belt 1 to resume discharging, the transition conveying belt 2 to start and stop and the bale opener feed conveying belt 3 to start and stop. The bale opener feed conveying belt 3 is provided with a material pushing mechanism (not shown in the figure, which can be the same as the existing structure).

[0029] In the embodiment, the sterilizer 100 is located at the right side of the bale opener 200, and the sterilizer discharge conveying belt 1, the transition conveying belt 2 and the bale opener feed conveying belt 3 run from left to right. Accordingly, the left side is the front, and the right side is the rear. The retreat of the material pushing mechanism refers to the bale opener feed conveying belt 3 driving the material pushing mechanism to run from left to right, leaving space, facilitating the transfer of the material from the transition conveying belt 2 to the bale opener feed conveying belt 3, and then pushing the material from the rear by the material pushing mechanism.

[0030] The material conveying device of the embodiment uses the transition conveying belt 2 to connect the sterilizer discharge conveying belt 1 and the bale opener feed conveying belt 3. The transition conveying belt 2 is provided with the feed detection member 21 and the discharge detection member 22 at both ends, which are used to control the sterilizer discharge conveying belt 1 to suspend discharging and the bale opener feed conveying belt 3 to retreat (specifically, in step S1, after the feed detection member 21 detects the material, the sterilizer discharge conveying belt 1 suspends discharging, and the bale opener feed conveying belt 3 drives the material pushing mechanism to retreat), and the sterilizer discharge conveying belt 1 to resume discharging (specifically, in step S3, after the material leaves the discharge detection member 22, the sterilizer discharge conveying belt 1 resumes running to discharge), the transition conveying belt 2 to start and stop (specifically, in step S2, when the discharge detection member 22 detects the material and the material pushing mechanism is not retreated in place, the transition conveying belt 2 suspends, and after the material pushing mechanism is retreated in place, the transition conveying belt 2 runs), and the bale opener feed conveying belt 3 to start and stop (specifically, in step S3, after the material leaves the discharge detection member 22, the bale opener feed conveying belt 3 runs). Even if the transition conveying belt 2 uses an ordinary motor and the sterilizer discharge conveying belt 1 and the bale opener feed conveying belt 3 use a servo motor, the collision between the material and the material pushing mechanism and the material accumulation problem can still be prevented, and the stable and smooth running of the material conveying device can be ensured.

[0031] In an embodiment, the feed detection member 21 and the discharge detection member 22 use photoelectric sensors, which can accurately determine whether the material is in place or leaves.

[0032] In another embodiment, the feeding detection member 21 and the discharging detection member 22 can also adopt a visual sensor, which can also be used to detect whether the material is in place or leaves.

[0033] In another embodiment, the feeding detection member 21 and the discharging detection member 22 can also adopt a travel switch, which can also be used to detect whether the material is in place or leaves.

[0034] Further, in the embodiment, the material conveying device further comprises a position detection member (not shown in the figure, which can also be a travel switch or various sensors) for detecting whether the pushing mechanism is returned to position, which is advantageous to ensure that the pushing mechanism is returned to position, thereby ensuring that the material can be transferred from the transition conveying belt 2 to the bale breaker feeding conveying belt 3.

[0035] Embodiment two

[0036] The conveying method of the material conveying device of the embodiment comprises the following steps:

[0037] S1, the transition conveying belt 2 is operated, and the sterilizer discharging conveying belt 1 is operated, the material after sterilization by the sterilizer 100 is conveyed to the transition conveying belt 2, after the feeding detection member 21 detects the material, the bale breaker feeding conveying belt 3 drives the pushing mechanism to return, thereby leaving space to facilitate the transfer of the material to the bale breaker feeding conveying belt 3, and the sterilizer discharging conveying belt 1 is temporarily stopped to avoid collision and accumulation of the material on the transition conveying belt 2;

[0038] S2, when the discharging detection member 22 detects the material and the pushing mechanism is not returned to position, the transition conveying belt 2 is temporarily stopped until the pushing mechanism is returned to position, and then the transition conveying belt 2 continues to operate to ensure that the material can be transferred to the bale breaker feeding conveying belt 3;

[0039] S3, after the material leaves the discharging detection member 22, the sterilizer discharging conveying belt 1 is operated, and the bale breaker feeding conveying belt 3 is operated, the material is transferred from the transition conveying belt 2 to the bale breaker feeding conveying belt 3 and located in front of the pushing mechanism;

[0040] S4, if the feeding detection member 21 does not detect the material, the bale breaker feeding conveying belt 3 drives the pushing mechanism to advance by a set distance, or in other words, the pushing mechanism drives the material to advance by one pitch, and such a cycle can push the last material to complete the related process of bale breaking, if the film cutting station of the bale breaker 200 detects the material, after completing the film cutting process, returns to step S1 (the pushing mechanism returns after the film cutting station completes the film cutting process, which is suitable for the working condition that the film cutting station and the pushing mechanism share the bale breaker feeding conveying belt 3, to ensure that the film cutting station successfully completes the film cutting of the material), if the film cutting station does not detect the material, directly returns to step S1.

[0041] The conveying method of the material conveying device of the embodiment controls the sterilization machine outfeed conveying belt 3 to pause outfeed and the unpacking machine infeed conveying belt 3 to back up, and the sterilization machine outfeed conveying belt 3 to resume outfeed, the transition conveying belt 2 to start and stop, and the unpacking machine infeed conveying belt 3 to start and stop, by means of the infeed detection member 21 and the outfeed detection member 22 at both ends of the transition conveying belt 2. Even if the transition conveying belt 2 adopts a common motor, and the sterilization machine outfeed conveying belt 1 and the unpacking machine infeed conveying belt 3 adopt servo motors, the material and the pushing mechanism can still be prevented from colliding, and the material can still be prevented from accumulating, so that the material conveying process is stable and smooth.

[0042] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art, without departing from the scope of the present application, can make many possible changes and modifications to the present application, or modify the equivalent embodiments. Therefore, any simple modification, equivalent change and modification made to the above embodiments without departing from the scope of the present application, should fall within the scope of the present application.
